Analog to digital converters (ADCs) are an important element in modern radio receivers and are therefore important in modem wireless base stations and user devices. Modern devices frequently use large scale integration, with integrated circuits being fabricated so as to include numerous components. Space on an integrated circuit is at a premium in such designs, and power consumption is also an important consideration. As wireless communication standards continue to evolve, analog to digital converters are becoming more numerous because mechanisms such as carrier aggregation (CA) use multiple receiver paths and therefore multiple ADCs. Therefore, a smaller ADC footprint and lower ADC power consumption greatly simplify the design of receivers using multiple ADCs. In addition, current and anticipated communication mechanisms allow for the use of different modes and bands resulting in different specifications (such as variable bandwidth and variable blocking conditions). Improved ADC designs that can accommodate such considerations can provide significant advantages in accommodating the needs of the systems in which ADCs operate.
